Ok, I'm almost caught up. I didn't get as much done as I would have liked...Smashboards seems to be have issues with saving edits to my second post...seems to be getting too big for its own good. (Yeah I know that Samus icon isn't working, I'd rather not try to save another edit just to fix it).
Dantarion, the database, is this something you'd think of integrating into your Custom Music Maker GUI? Or is this a website you're suggesting designing? We've had a little talk about how we can move the music list outside the forum. Ideally it'd be done in a way such that users can submit their songs with information for each song (as they do now) all the formatting is done for them as things are arranged on a table. Users can edit their own submissions to update them. Submissions can be rated. Etc.
While I think we are doing a pretty darn good job with this topic at centralizing the music modifications made by everyone in such a way they they are all easy to browse through, preview, and download in one spot, the texturing modding community seems to be much more branched. I personally find it taxing to have to sift through 10 websites, plus forum threads, just to see what's out there.
The best attempt I can see is the Brawlhacks Wiki
http://brawlhacks.wikia.com/wiki/Meowmix_Wiki but the formatting could use some work (for music at least). It's a commendable one, definitely, but could use more work.

I'd also like to point out to anyone who supports this thread and the centralization of custom music could further support it by including a link to it with a small description on the custom music threads they are hosting. If your thread isn't in my links already, be sure to let me know. Everyone wins.
